HUMIDIFIER.

Application filed April 24,

To all whom it'may concern Be it known that I, DUNCAN MACKENZIE ANDERSON, of the city of Toronto, in the county of York, in the Province of Ontario, 'Canada, have invented certain new and useful Improvements in Humidifiers, of which the specification.

My invention relates to improvements in humidifiers and the object of the invention is to devise a simple means whereby a maximum amount of moisture may be imparted to the-heated air of a room and which will operate automatically and dispense with the need of attendants to keep it supplied with water and at the same time to devise a simple device which may be set in place by an unskilled person and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Figure 1 is a perspective view of a radiator of a hot water system showing my device applied thereto.

Fig. 2, is an end elevation of the upper portion of a radiator and my device.

Fig. 3, is a sectional detail of a perforated water feeding tube and a portion of a fabric curtain supported thereby.

' Fig. 4, is a sectional detail showing the means of connecting the water supply pipe to the drip cock spout of the radiator.

In the drawings like characters of reference indicate corresponding parts in the various figures.

1 indicates a radiator provided with the usual drip cock 1" provided with a drip spout 1 and with the usual valve controlled by the valve handle 1 1 indicates the stem and 1 the nut by which the handle is secured upon the stem. '2 indicates a lever which is preferably of inverted V-shape form having a hole which the stem 1 extends.

In order to place the lever in position the nut 1* is removed from the valve stem and the lever 2 slipped on to the stem and the nut rescrewed on to the stem, clamping the lever rigidly inplace. The rearwardly extending. arm 2* of the lever is provided at its lower end with a hook 2". The forwardly extending arm 2 is provided with a weight 2, which is slidable thereon and held in position by a set screw 2 3 indicates a perforated tube provided with closed ends and preferably comprising Specification of Letters Patent.

erably for-med of flexible metal and which connects the nipple 3" extending from the outer end of the tube 3 to the depending spout 1 of the drip cock 1". The tube 5 is secured to the spout by any suitable means such as by a set screw 6.

7 indicates a curtain of coarse mesh fabric which is thrown over the perforated tube 3 so as to depend on each side of the tube behind the radiator 1.

Having described the principal parts volved in my invention I will brlefly scribe the operation of same.

The water passes from the open drip cock through the spout 1 into the tube 5 and erforated tube inde- 3 passing through the per orations tube 3 into the curtain 7 which absorbs such water and the heat of the radiator causes the water held by the curtain to evaporate quickly and thereby supply the heated air with moisture as it rises. If the supply of Water to the curtain is not sufficient to keep it moist the curtain will gradually dry out and, therefore, become llghter in weight, the weight of the curtain being counterbalanced by the weight 2 causing the arm 2' to drop and the arm 2* to rise. By this movement the arm 2 which is rigidly secured to the valve handle 1 turns the valve handle so as to further open the valve, supplying a greater amount of water to the 01114334111. Contrariwise if the curtain becomes too moist its weight carries the arm 2* downwardly lifting the weight 2 and turning the valve handle 1 in the opposite direction to more or less close the valve.

From this description it will be seen that I have devised a very simple device whereby a maximum amount of moisture may be supplied to the air of a heated room, the moisture suppliedtothe curtain being auto: matically controlled so that it is constantly kept in a sufficiently moist condition. The amount of moisture may-be regulated by adjusting the weight 2 upon the arm 2 so as to give a greater or less amount of leverage, the farther out the weight being held of the p upon the arm 2- the greater the weight of water will be required in the curtain to lift such weight toclose the valve and the farther up the weight 2 is upon the arm 2 the smaller the weight of water in the curtain required to lift such weight.

What 'I claimas my invention is I '1. In a humidifier, the combination of a radiator, a perforated tube supported behind the radiator, means for conducting water from the radiator into the tube, a water absorbing curtain hung upon the tube and valve means automatically controlled by the weight of'the water in-the curtain and L adapted to regulate the passage of' water through said conducting means.

2.- Ina humidifier, the combination with i the radiator, the radiator drip cock probracket supporting from the radiator, a lever rigidly secured and a handle for conof a perforated tube, a one end of the tube vided with a valve, trolling the valve,

against the face of the controlling valve handle and provided at one end with a weight and adapted to support the perforated tube at the opposite end, a duct connection between the drip cock spout and the perforated tube, and a water absorbing curtain hung upon the tube so as to depend at each side thereof.

3. In a humidifier, the combination with the radiator, a radiator drip cock provided with a valve, and a handle for controlling the valve, of a perforated tube, a bracket supporting one end of the tube from the radiator, a lever arm rigidly secured to the face of the controlling valve handle and provided at one end with a weight and adapted to support the perforated tube at the opposite end, a duct connection between the drip cock spout and perforated tube, and a water absorber adapted to receive water from the perforated tube.
